The Yakuza 2 remake first launched in Japan in December 2017. It uses the same engine as Yakuza 6: The Song of Life. Here an overview of the game, via Sega:

About

It’s been a full year since Kazuma Kiryu took his leave from the world of the yakuza during the events of Yakuza: Kiwami. Fate, however, has other things in mind for the legendary Dragon of Dojima, and Kiryu finds himself back on the front lines of a potential all-out war, as SEGA proudly presents Yakuza: Kiwami 2, one of the most beloved storylines in the franchise’s history, remade in full HD for the PlayStation 4.

From the global development studio that introduced the world to Kazuma Kiryu, Ryu Ga Gotoku returns in high form with Yakuza: Kiwami 2. The game will be releasing both physically and digitally on the PlayStation 4 on August 28, 2018 for $49.99. That’s not all, though – pre-orders and first-run copies of Yakuza: Kiwami 2 will come in an elaborate SteelBook featuring Kiryu and his fierce rival, the Dragon of Kansai, Ryuji Goda.

For an in-depth look at the world of Yakuza, or for a refresher on key personalities and story moments throughout the series, be sure to check out the Yakuza Experience Website. There, you can experience the story through a 10-part interactive digital comic series as well as comprehensive character maps and timelines. Visit the Yakuza Experience Website here.

Key Features

Dragons Belong on the Dragon Engine – Yakuza: Kiwami 2 is a re-creation of the original Yakuza 2, completely rebuilt in the Dragon Engine, the same engine used in developing Yakuza 6: The Song of Life. Experience gorgeous graphics on top of seamless transitions between battles or when entering or leaving buildings. All cutscenes and key voiced lines have been re-recorded to be as true to the original as possible, while reaping the benefits of the most powerful engine the Yakuza series has ever seen. Big Hits, Minigames – Kiryu hasn’t let his time away from the front lines dull his skills in combat or leisure. Pull off a wide variety of brutal (and hilarious) Heat Actions, and challenge new minigames such as Golf Bingo, the original arcade release of Virtual-On, the return of Yakuza 0‘s much-celebrated Cabaret (including the return of fan-favorite Yuki!), Majima’s revamped Clan Creator, and even Sega’s infamous Toylets! Unveil the Truth of Goro Majima – This time around, Kiryu isn’t the only one running the show – fans of the Mad Dog of Shimano won’t want to miss this new Majima-centric campaign, which features Majima as a playable character, complete with his trusty dagger, and sheds light on his personal journey from the end of Yakuza: Kiwami up to Yakuza: Kiwami 2. Extreme Localization – We’ve gone through the Yakuza: Kiwami 2 script with a fine-toothed comb; every effort has been made to ensure that it’s the most faithful representation of the original Japanese. Sega is committed to supporting the best Yakuza experience possible for the series’ dedicated fans around the world.

Kiwami and K2 are remakes. 6 is a proper squeal to 5 which was released in 2015 (2012 in Japan), and 0 was a freshly released prequel. We then have Fist of the North Star which hasn't yet been announced for the west (but is out in Japan now, I think) and isn't directly connected to Yakuza but is by the same team and will very much play like a Yakuza game. Then we have the yet to be properly shown Yakuza 7. (All we really know of that is it will have a new protagonist.) Clearly the answer is not nearly enough!

Goddamn if they announce Kiwami 3! Sunshine Orphanage and 7 Mysteries of Downtown Ryukyu in Dragon Engine would be just :hngh:

There are also a couple of PSP games, a couple of period set games and a survival horror spinoff subtitled Dead Souls.

The game which Sega all but used as an excuse to kill off the series in the west. Dark days. (For those who aren't aware: it was a tank controls monster shooter which sold extremely poorly. Sega said it showed there wasn't an appetite for the series proper in the west and didn't announce Yakuza 4 localisation. Then along games Sony's Gio Corsi and their #BuildTheList campaign and the rest of history )

Would love a localisation of Ishin (Yakuza set during tail end of Edo period) but I think that's gonna be very unlikely now
